Application February 16, 1955, Serial No. 488,556

1 Claim. (Cl. 299-140) This invention relates to a new and improved nozzle for oil burners, and the principal object of the present invention resides in the provision of a simplified device of the class described which is more economical in operation and less expensive to maufacture; the provision of a nozzle of the class described comprising a simple pipe 'or tube substantially flattened at one end thereof and flaring outwardly wider than the tube, said flattened portion having a relatively long narrow orifice through which oil under pressure is forced outwardly to provide the flame; the provision of a nozzle as above described, in combination with a double pipe arrangement provided with separate valves for leading oil and steam or air under pressure to a common point for leading into the pipe or tube aforesaid, said pipe being connected to the double inlet air and oil pipes by means of a union, so that the flame is from the location of the union and the point of juncture of the oil and steam or air under pressure.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a view in side elevation of a device according to the present invention;

Fig. 2 is a plan view thereof;

Fig. 3 is a greatly enlarged view of the forward end of the nozzle, looking in the direction of arrow 3 in Fig. l; and

Fig. 4 is a section on line 44 of Fig. 3.

In carrying out the present invention, there are pro vided a pair of pipes indicated at and 12, each of these pipes being provided with a separate valve 14 for controlling the in-flow of fuel oil in one pipe and steam or air under pressure in the other. The two pipes join in a T 16 to which is secured a union having a nut 18.

A part of the union which comprises a threaded fitting 20 is fixed at the end of an elongated pipe or tube 22, so that the latter is removable from the nut 18 of the union, and a pipe or tube of a different length may be attached if desired. The other end of the pipe or tube Patented Aug. 14, 1956 22 is flattened as shown at 24 and terminates in an opening 26 through which issues the atomized oil to form a flat flame as indicated at 28 in Fig. 2.

This flat flame is occasioned by the fact that the flattened tube provides an elongated narrow straight opening or slit for the atomized oil as clearly shown in Figs. 3 and 4. The ends of the opening are cut away as at 28 at the sides of the flattened area 24 to provide for the widening of the flame as shown in Fig. 2.

In flattening the end of the pipe or tube 22, the same provides a pair of lips or the like as shown in Fig. 4 and these are preferably centrally transversely cut at 30 in a vertical direction to provide a cross flame which is indicated in part at 32 in Fig. 1.

The two pipes 10 and 12 are provided with a transverse bracket 34 to which is connected a forwardlyextending bracket 36 for supporting the apparatus in a convenient location with respect to an opening in the furnace to which the device is to be applied.

It will be seen that this invention provides a very simple oil burner nozzle which may use steam or air under pressure to atomize the oil, said nozzle being excep tionally free from carbon, so that the device may be used in operation for a long time without the necessity of cleaning the orifice.

The nozzle has been found to be extremely economical in actual operation and results in a saving of fuel as well as providing for a greatly simplified nozzle construction which may be made principally of pipes and fittings which are customarily at hand or easily obtainable.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

An oil burner comprising a hollow, empty, elongated tubular pipe-like member, one end thereof being flattened and providing a pair of lips spaced apart and forming a transverse elongated narrow slit-like opening for the issuance of atomized oil, a connection for the member to separate sources of liquid fuel and steam or air under pressure, said connection comprising a T- shaped pipe, a union attached to the leg of the T, said tubular member being attached to the leg of the T by the union, slits in the side edges of the flattened end of the pipe and a central transverse slit in each lip.
